摘要:
The present invention relates to an adhesive article which can be used as a layer in or a cover for various articles in which a hydrophilic or hydrophobic surface is desired. The adhesive article includes a base layer having a first surface and a second surface and a coating layer formed on the first surface of the base layer, where the coating layer contains at least one adhesive resin and at least one hydrophilic polymer; at least one adhesive resin (which can be a hydrophobic polymer) and at least one surfactant; or at least one adhesive resin, at least one hydrophilic polymer and at least one surfactant. Given the application, the coating layer can be formulated to provide either a hydrophilic or hydrophobic surface. The polymer portion of the coating provides the coating layer with sufficient hydrophilic properties to increase the rate fluid transport across (or in the area near) the coating layer.

Various aqueous top coat compositions are described. The compositions include one or more polyurethane dispersions, silica, crosslinker(s), acrylic polymers, and an optional water soluble polyester. The compositions can be used to form top coats which exhibit good resistance to scratches and solvents, and improved ink retention.

A composition that is configured for use in creating a film. The composition includes a vinyl acetate containing polymer, such as a vinyl acetate ethylene (VAE) copolymer, fire retardant additives and at least one additive that is a pigment, a surfactant, a dispersant, a wetting agent, a defoamer, a coupling agent, a solvent, a UV absorber, a fire retardant, or a light stabilizer.

The current invention utilizes an extrusion coating method as a key step in a series of multilayer construction processes to make a laminate for graphic application. The extrusion coated layer performs as a strengthening layer to provide mechanical properties for the construction, while an ink receptive coating layer delivers high quality printability performance. High gloss can be achieved through the use of a PET carrier.

This disclosed invention relates to a dry paint transfer laminate, comprising: a dry paint film layer comprising a binder and a pigment, the dry paint film layer having an upper surface and a lower surface; an adhesive layer overlying the upper surface of the dry paint film layer; and a release liner overlying the lower surface of the dry paint film layer. Methods of making and using the laminate are disclosed.

This invention relates to labels. In one embodiment the labels comprise a polymer facestock layer, a nano-porous layer underlying the facestock, and an adhesive layer underlying the nano-porous layer. In another embodiment, the labels comprise a polymer facestock layer, a nano-porous layer underlying the facestock, and a metal layer overlying the facestock or underlying the facestock between the facestock and the nano-porous layer. These labels can be bonded to substrates of glass, plastic, or metal using a water based adhesive which is in contact with the nano-porous layer.
摘要:
Methods and/or systems for printing or otherwise evincing temporary indicia on media with disappearing inks are described along with suitable disappearing ink formulations and media constructions for executing the same. In particular embodiments, the methods and/or systems described employ a plurality of disappearing inks with different disappearing rates. In one embodiment, a barrier layer that is selectively used to cover a major surface of the media is employed to substantially block or otherwise regulate a rate of phase transitions (e.g., evaporation and/or sublimation) experienced by ink borne by the media.

This disclosed invention relates to a method of making a dry paint transfer laminate, comprising: applying a paint film layer over one side of a release liner and drying or curing the paint film layer, the paint film layer comprising a binder and a pigment, the paint film layer having an upper surface and a lower surface, the release liner having a release surface, the lower surface of the paint film layer overlying the release surface of the release liner; and applying an adhesive layer over the upper surface of the paint film layer.
摘要:
Ink receptive substrates comprise a base layer formed from a water-insoluble thermoplastic polymer, and an ink receptive layer disposed over the base layer. The ink receptive layer is formed from a melt processable blend of a water-soluble polymer and a substantially water-insoluble polymer, and provides an inherently ink receptive surface without further surface treatment. The ink receptive blend comprises in the range of from 20 to 80 percent by weight water-soluble polymer, and in the range of from 20 to 80 percent by weight substantially water-insoluble polymer based on the total weight of the blend. The blend has a melting temperature in the range of from about 100 to 600° F. Preferred water-soluble polymers include polyvinyl alcohols and polyalkyl oxazolines. Preferred ink receptive substrates of this invention comprise a base layer and ink receptive layer that are formed simultaneously by coextrusion process. Ink receptive substrates of this invention can include the ink receptive layer on one or both surfaces of the base layer, and/or can be constructed in the form of a pressure-sensitive adhesive label, i.e., with a pressure-sensitive adhesive material disposed on a surface of the base layer opposite the ink receptive layer.
